after playing around with gentoo for some weeks now i now have heavy stability problems.
I can't do any 3d without system lockup + xid:nvrms in the message log.ck tomy

Ok, back to my second install (which i used for 2 years now without problems), and OUCH
i have terrible issues there also. I can't even get into kde, cause the x server crashes randomly. I have tons of artefacts and horizontal full coulured lines on the screen( those are moving around).
